Jannis Harder	5042600c0d	xprop, setundef: Mark xprop decoding bwmuxes, exclude them from setundef ... This adds the xprop_decoder attribute to bwmuxes that drive the original unencoded signals. Setundef is changed to ignore the x inputs of these bwmuxes, so that they survive the prep script of SBY's formal flow. This is required to make simulation (via sim) using the prep model show the decoded x signals instead of 0/1 values made up by the solver.	2023-01-11 18:07:16 +01:00
